For this year's Burning Man the folks who run the More Carrot Theme Camp have created Illuminatrix, an LED matrix art installation and want your animation contribution. The site has an online editor to create or even re-create one of your existing pixelart animation. Deadline is Aug 26, 2010.
Even if you don't attend Burning Man, after the festival, videos will be posted of the art installation.
I made one!

Cool idea, but the editor is kinda cumbersome :/ I wish you could import frames.
That's a good one BB.
